BEARING-.SLEEVE FULLER.

Application filed September T0 all whom il mayV concern Be it known that Vl, DAVID O. liliLLnn, a citizen of the United Viiitates, residing at Maclsville, in the the county of Stafford and State of Kansas, have invented certain new and useful Improvements in a Bearing- Sleeve Puller, of which the following is a specilication. Y 'y This invention relates to improvements in sleeve pullersj and is more particularly adapted to a device for extracting bearing sleeves from the rear axle housing of a motor vehicle.

One of the important objects of the present invention is to provide a bearingsleeve puller of the above mentioned character, which may be readily and easily placed in use and will enable the bearing sleeve to be removed from the axle housing without any danger of the sleeve becoming injured, the device being further of such construction as to prevent any possibility of the sleeve becoming disengaged from the puller during the removal ofthe sleeve from the aXle housing.

A still further object of the invention is to provide a bearing sleeve puller of the above mentioned character, which is simple in construction, inexpensive, strong and durable and furthermore adapted for the purposes for which it is designated.

Gther objects and advantages of this invention will become apparent during the course of the following description.

ln the accompanying drawing forming a part of this specification and in which like numerals designate like parts throughout the same:

Figure 1 is a side elevation of my `improved bearing sleeve puller showing the same in position within a sleeve.

Figure 2 is a sectional view taken approximately on line 2 2 of Figure l.

Figure 3 is an enlarged fragmentary scctional view of the head member or section showing the spring pressed stud mounted therein, and

Figure 4l is an end elevational view of the head supporting member.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my'invention, the numeral l designates the head section, the same being s, 1924. serial no. 736,548.

substantially semi-circular in cross section and asis clearly illustrated in Figure 2. The head section is provided with a vertically extending opening 2 adjacent the for` ward end thereof and a pin 3 extendstransversely through the central portion of the opening and provides a means for support-- ingthe spring pressed studor plunger/t 1in the opening, a coilv spring 5 normally holding the studnpwardly of the upper surface of thehead member as clearly illustrated in Figure 3. The purpose of the spring pressed stud will hereinafter be more fully describech Screw .threaded in the `rear end `of .the head section lis the forward end of the elongated rod 6. The rear end of the rod is connected to a suitable operating rod 7 for facilitating the removal of the bearing sleeve designated generally yby the letter A from the housing B in the manner to be presently described.

For the purpose of supporting the head section against lateral movement when the same is within the bearing sleeve, I provide the semi-circular supporting member 8, the free edges of which are adapted to engage the free edges of the semi-circular head section l, the supporting member 8 being in serted within the bearing sleeve by means of the handle 9 which has its forward endV threaded into a suitable opening provided in the rear portion of the supporting member 8. In use, the head section l is inserted within the bearing sleeve around the upper half of the axle C and during the insertion of the head section within the sleeve, the stud 4: is depressed against the tension of the coil spring until the stud comes into registry with the opening provided in the bearing sleeve whereupon it automatically moves out into engagement with the opening. The locking or supporting member 8 is then inserted within the bearing sleeve around the lower half of the axle until the upper edges of the supporting member engage the lower edges of the head section l, the member 8 thereby acting in the capacity of a wedge for locking and securing the head section in engagement with the bearing sleeve and further preventing the move` ment of the head section within the sleeve. By tapping on the thickened portion `10 of the lever 7, the head section l and the bearing sleeve A will be moved outwardly from the housing C Without any danger of the bearing sleeve becoming injured during the removal thereof.

IIeretoi'ore, considerable time and labor have been spent in removing Worn bearing sleeves from axle housing and oftentimes during the removal of such bearing sleeves, the same have become broken or damaged to such an extent as to render the same useless. rEhe Vprovislon of a bearing sleeve puller of the above mentioned character,

will save considerable time and labor in the removal of the bearing sleeves from axle housings and the parts are further so arranged as to enable the .same to be readily assembled or disassembled. The necessity of removing the rear axle in order to gain access to the bearinesleeve is also obviated when the bearing sleeve puller of the above mentioned character is employed.

lWhile I have shovvl'i the Vprei'erred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to Without departing` from the spirit of the invention and the scope of the appended claim.

Having thus described the invention, what I ealim is A bearing sleeve puller comprising a head section adapted to be inserted into the sleeve to be pulled, said section being relatively long and substantially semi-circular in cross section, a rod detachably connected to the outer end of said section and extending outwardly therefrom, a lever pivotally connected to the outer end oi the rod, saidy lever comprising a handle, and a block-like connection between the handle and rod, said connection forming an impact member which is adapted to receive the blows from a hammer used in driving out the sleeve, and a supporting member for said head sec-- tion, said supporting member being senncircular in cross section, and comparatively short in length to permit it to be engaged with the intermediate portion or .said lirst named section, and a handle forming rod connected to said supporting member.

In testimony whereof I afiix my signature.

DAVID O. MILLER.
